Porcine and Chicken Intestinal Epithelial Cell Models for Screening Phytogenic Feed Additives—Chances and Limitations in Use as Alternatives to Feeding Trials. Microorganisms 2022; 10:microorganisms10030629. [PMID: 35336204 PMCID: PMC8951747 DOI: 10.3390/microorganisms10030629] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 03/11/2022] [Accepted: 03/12/2022] [Indexed: 02/07/2023] Open
Abstract
Numerous bioactive plant additives have shown various positive effects in pigs and chickens. The demand for feed additives of natural origin has increased rapidly in recent years to support the health of farm animals and thus minimize the need for antibiotics and other drugs. Although only in vivo experiments can fully represent their effect on the organism, the establishment of reliable in vitro methods is becoming increasingly important in the goal of reducing the use of animals in experiments. The use of cell models requires strict control of the experimental conditions so that reliability and reproducibility can be achieved. In particular, the intestinal porcine epithelial cell line IPEC-J2 represents a promising model for the development of new additives. It offers the possibility to investigate antioxidative, antimicrobial, anti- or pro-proliferative and antiviral effects. However, the use of IPEC-J2 is limited due to its purely epithelial origin and some differences in its morphology and functionality compared to the in vivo situation. With regard to chickens, the development of a reliable intestinal epithelial cell model has attracted the attention of researchers in recent years. Although a promising model was presented lately, further studies are needed to enable the standardized use of a chicken cell line for testing phytogenic feed additives. Finally, co-cultivation of the currently available cell lines with other cell lines and the development of organoids will open up further application possibilities. Special emphasis was given to the IPEC-J2 cell model. Therefore, all publications that investigated plant derived compounds in this cell line were considered. The section on chicken cell lines is based on publications describing the development of chicken intestinal epithelial cell models.

Prevention of infection caused by enteropathogenic E. coli O157:H7 in intestinal cells using enrofloxacin entrapped in polymer based nanocarriers. JOURNAL OF HAZARDOUS MATERIALS 2021; 414:125454. [PMID: 33677317 DOI: 10.1016/j.jhazmat.2021.125454] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 01/27/2021] [Accepted: 02/15/2021] [Indexed: 06/12/2023]
Abstract
Poor bioavailability of antibiotics, toxicity, and development of antibiotic-resistant bacteria jeopardize antibiotic treatments. To circumvent these issues, drug delivery using nanocarriers are highlighted to secure the future of antibiotic treatments. This work investigated application of nanocarriers, to prevent and treat bacterial infection, presenting minimal toxicity to the IPEC-J2 cell line. To accomplish this, polymer-based nanoparticles (NPs) of poly(lactide-co-glycolide) (PLGA) and lignin-graft-PLGA (LNP) loaded with enrofloxacin (ENFLX) were synthesized, yielding spherical particles with average sizes of 111.8 ± 0.6 nm (PLGA) and 117.4 ± 0.9 nm (LNP). The releases of ENFLX from PLGA and LNP were modeled by a theoretical diffusion model considering both the NP and dialysis diffusion barriers for drug release. Biocompatible concentrations of ENFLX, enrofloxacin loaded PLGA(Enflx) and LNP(Enflx) were determined based on examination of bacterial inhibition, toxicity, and ROS generation. Biocompatible concentrations were used for treatment of higher- and lower-level infections in IPEC-J2 cells. Prevention of bacterial infection by LNP(Enflx) was enhanced more than 50% compared to ENFLX at lower-level infection. At higher-level infection, PLGA(Enflx) and LNP(Enflx) demonstrated 25% higher prevention of bacteria growth compared to ENFLX alone. The superior treatment achieved by the nanocarried drug is accredited to particle uptake by endocytosis and slow release of the drug intracellularly, preventing rapid bacterial growth inside the cells.

Abstract
Lythrum salicaria herb (LSH) was applied in diarrhea therapy since ancient times. Despite empirically referenced therapeutic effects, the bioactivity mechanisms and chemical constituents responsible for pharmacological activity remain not fully resolved. Taking into consideration the historical use of LSH in treatment of diarrhea in humans and farm animals, the aim of the study was to examine in vitro the influence of LSH and its C-glycosylic ellagitannins on processes associated with maintaining intestinal epithelium integrity and enteropathogenic Escherichia coli (EPEC) growth and adhesion. LSH was not only inhibiting EPEC growth in a concentration dependent manner but also its adhesion to IPEC-J2 intestinal epithelial cell monolayers. Inhibitory activity toward EPEC growth was additionally confirmed ex vivo in distal colon samples of postweaning piglets. LSH and its dominating C-glycosylic ellagitannins, castalagin (1), vescalagin (2), and salicarinins A (3) and B (4) were stimulating IPEC-J2 monolayer formation by enhancing claudin 4 production. Parallelly tested gut microbiota metabolites of LSH ellagitannins, urolithin C (5), urolithin A (6), and its glucuronides (7) were inactive. The activities of LSH and the isolated ellagitannins support its purported antidiarrheal properties and indicate potential mechanisms responsible for its beneficial influence on the intestinal epithelium.

Abstract
Cysteine-rich intestinal protein 1 (CRIP1) is an important transcriptional regulation factor during the tumor development. Although it was largely studied in the human or mouse, no report has provided functional evidence for it in the swine. To date, the real sequence of porcine CRIP1 (poCRIP1) was also still unknown. In this study, clear characteristics for the poCRIP1 were represented. A 552bp poCRIP1 cDNA was obtained from porcine brain tissue using real time reverse transcriptase PCR. The poCRIP1 showed 89% and 93% homologous with human and cattle, respectively. And it also contained one conserved domain, LIM-CRIP domain. Meanwhile, the genomic structure and promoter map was done and several conserved transcriptional regulatory sites were also predicted in this study. The expression pattern of poCRIP1 indicated that poCRIP1 is expressed in mucosal tissue. An infection experiment about the gut was designed to analyze whether or not poCRIP1 was functional in gut immunity, and an interesting result was that poCRIP1 was only activated by an opportunistic pathogen, Enterococcus faecalis FA2-2. It was the first report to identify the full-length sequence of poCRIP1 gene, represent a clear characteristic and immunologic role of CRIP1 in domestic animal until now.

Abstract
Medium-chain fatty acids (MCFAs) have been suggested as an alternative to the use of antibiotics in animal nutrition with promising results. First, we studied the sensitivity of Salmonella Enteritidis and an enteropathogenic Escherichia coli strain against caprylic (C8), capric (C10) and lauric (C12) acids. A porcine in vitro model using the porcine cell line IPEC-J2 was used to test the effects of MCFAs on structural and immunological traits without and with a concomitant challenge with E. coli or S. Enteritidis. The three MCFAs exerted an inhibitory effect on bacterial growth, stronger for C12 than C8 or C10, S. Enteritidis being more sensitive than the E. coli strain. Flow cytometry showed a numeric concentration dependent increase in the adhesion of E. coli or S. Enteritidis to IPEC-J2 cells. Measurement of transepithelial electrical resistance after bacterial challenge showed negative effects of all MCFAs on IPEC-J2 cells at the highest concentrations. Immune parameters were affected by C8, since a concentration dependent effect starting at 5 mM was observed for mRNA expression of IL-6 and TLR-4 (up-regulated) and IL-8 (down-regulated). TLR-4 was up-regulated with C10 at 2 and 5 mM. The three MCFAs affected also the epithelial morphology through down-regulation of Occludin and up-regulation of Claudin-4 expression. In conclusion, the three MCFAs under study influenced bacterial growth rates and modified the gene expression to a different degree in the cell line IPEC-J2 but the effect on the morphological structure and response of the cells after bacterial challenge could not be assessed. Although these tests show a prior estimation of MCFAs effects in intestinal epithelium, in vivo confirmation is still needed.
